Description
Technical field
The invention belongs to machine components technical field of processing equipment more particularly to a kind of revolution jigs and clamping workpiece
Method.
Background technology
Jig is that machine-building is used for fixing processing object in the process, is allowed to occupy correct position, to receive to apply
Work or the device of detection.In a broad sense, any process in technical process, for it is rapid, workpiece is easily and safely installed
Device, all can be described as fixture.Such as welding fixture, inspection jig, assembling jig, jig etc..Wherein jig is most
It is common, is often simply called fixture.When machining a workpiece on a machine tool, to make the surface energy of workpiece reach size as defined in drawing, several
What shape and with the technologies requirement such as the relative-position error of other surfaces, workpiece must be installed before processing（Positioning）, clip
（It clamps）.
Patent No. CN201189565, applying date 2008-04-28 are disclosed a kind of for parts on lathe positioning
The fixture of clamping, it includes sequentially connected hydraulic power chuck, chuck supports block, master jaw and claw, for holding parts
Claw is flexibly connected by bindiny mechanism with master jaw.
Above-mentioned patent provides pressure oil input by hydraulic pump so that claw is made according to the black skin shape of clamped part
It is micro to swing firmly to clamp part.But with chuck（Three-jaw or four paws）It is aided with centre frame and top clamping blank,
The only clamping force of chuck and the top pressure of blank are fastened, thus machining blanks part is in the work of cutting force and top power
Relative displacement may occur with chuck under, including opposite rotation is unsceptered and moves axially, cause processing part rejection.
Invention content
It is an object of the invention to overcome the above-mentioned problems in the prior art, a kind of revolution jig and dress are provided
The method for pressing from both sides workpiece, the fixture can prevent that blank type relative rotation is unsceptered in process or axial direction moves,
And it is simple in structure, the time that changes the outfit is short, is accurately positioned, and versatility is good.
To achieve the above object, the technical solution adopted by the present invention is as follows.
A kind of revolution jig, including main shaft connector, blank and top, it is characterised in that：The main shaft connection

End is connect with hydraulic joint, and the other end is connected to centre bore, and the hydraulic joint is connected with hydraulic pump, is installed on the centre bore
There are blind rivet, the main shaft connector that anti-rotation locating piece has been bolted, has been provided on the anti-rotation locating piece and matches with keyway
The positioning key of conjunction, the anti-rotation locating piece are fixedly connected with the end face of blank, be provided on the end face of the blank with
The pre-manufactured hole that blind rivet is fixedly connected, the other end of the top secured blank part.
The anti-rotation locating piece is achieved a fixed connection with blank by slot falcon, and falcon head, institute is arranged in the anti-rotation locating piece
State the falcon mouthful being provided on blank with falcon head cooperation.
The keyway is set as 4, and the width of one of keyway is more than the keyway of the other three equal in width.
The blind rivet is connect with pre-manufactured hole using being screwed.
A method of revolution jig clamping workpiece, it is characterised in that：Include the following steps：
1）Zero-point positioning module is mounted in the locating ring on main shaft connector, is combined into clamp base, and zero is fixed
Centre bore in the module of position is connected to the hydraulic channel of main shaft connector；
2）Clamp base is threadedly attached in machine tool chief axis end face；
3）Hydraulic channel is connect by pressing from both sides hydraulic joint with hydraulic pump is connect；
4）By in the positioning key insertion keyway on anti-rotation locating piece, then anti-rotation locating piece is tightened by bolt and is connected in main shaft
On junctor；
5）One end of blind rivet is connected through a screw thread in the pre-manufactured hole being fixed on blank, then puts the blind rivet other end
In the falcon mouthful on the embedded blank of falcon head in the centre bore for entering zero-point positioning module, while on anti-rotation locating piece；
6）Start hydraulic pump, one end by hydraulic pump by blind rivet together with blank tenses in clamp base；
7）By the top other end for compressing blank of tailstock tool.
Advantage using the present invention is：
1, being accurately positioned and tensing for blank is realized by hydraulic pump and blind rivet, prevents blank in process from sending out
Raw axial movement, while workpiece origin can be fixed at the machine tool chief axis centre of gyration and anti-rotation locating piece end face by fixture
Intersection point, using after blank clamping without looking for Cutter coordinate system again, with fixed one or more coordinate systems complete journeys compile and
Processing is suitable for batch production, by the end face of anti-rotation locating piece secured blank part, prevents blank in process from axis occurs
To unsceptered, and hydraulic pump quickly can start and close, and provide release for zero-point positioning module or tense the power of blind rivet, dress
It unloads conveniently, the time that changes the outfit is short.
2, it is fixedly connected by slot falcon, close and firm, while again so that processing, being easy to assembly.
3, it is more than the keyway of the other three equal in width by the width of a keyway, direction when installation is avoided to misplace.
4, it is used and is threadedly coupled with pre-manufactured hole by blind rivet, easy to loading and unloading, stability is high.
5, conventional scroll chuck, chuck or collet clamping method are solved in Milling Process complexity revolving meber
Shi Xuanzhuan loses its position and leads to workpiece overproof the problem of scrapping；Compared with conventional special tooling, the present invention realizes general
Property, due to realizing quick Set and Positioning comprising Zero-point positioning system, processes complex part for revolution class numerical control machine tool and provide
The outer clamping of realization machine, fast changes the base interface of part, solves revolution class lathe special fixture and replaces trouble, alignment time is long in machine
The problem of, it is easy to accomplish flexible automation produces；Compared with current international common zero-point positioning chucking appliance system, the present invention only needs
It wants a zero-point positioning clamping unit, positioning holddown pin to be directly installed on workpiece, transition clamp need not be installed on workpiece
Tool reduces the outer clamping work of machine and carries weight, reduces production and carry difficulty, easy to use.
